I have a new JacksonRacing supercharger. But I have herd that a turbo makes more power for the GSR... What do you think??

 

turbo will always make more power than sc, the power band for a sc is very linear

 

Turbo....
Supercharger has a limit on how fast you can build your car. All you can do is get a bigger pulley. I'm not a big fan of superchargers at all.
Turbo, you can build your engine and up the boost. (Drivetrain, ecu, and other stuff too)

 

Well you won't hit 9s with a supercharger if thats what you are wondering. 13s easy and probably not a problem hitting 12s either.

 

As long as u get a centrifugal supercharger u can run upwards of 15 psi... but like a turbo it wont make power till 3 grand or so... but in the long run it doesnt loose power at higher rpms like turbo's do... and it wont lag... also u can run slightly higher compression making up for the power loss off the line...

 

where did you get the part of losing power at higher rpms from?

 

Most superchargers are extremely inefficient because of the heat they generate. We think 130 degree F charge is hot for our high boost turbo cars but that's nothing when you see how much heat a SC can make. We stopped building SC Hondas a long time ago because we were seeing intake air temps above 200 degrees (approaching 240) and you're never going to make power that way. Everything FI we do now is turbo and it's not hard at all (just a little time and money) to make a 700whp+ street car. The people that bitch about turbo and talk about how great SC's are probably haven't even driven a turbo car, it's not that big of a deal even with a BIG turbo on the street.

 

What do you think my car will run with my Jackson racing supercharger?? With an 8 Psi pully. 3 Puck clutch, MSD btm, and adj. cam gears, On street tires???

 

you would have to bring it to the track and see, numbers won't lie to you

 

what do u thnk intercoolers and aftercoolers are for??? but thing is technolog has changed and superchargers will make a come back... now if they will ever be better then a fully built turbo'd vehicle i dont think so.

i guess when my SC'd car is done we will see...

 

Again at the time they didn't have a lot of the aftercooler, etc. stuff out so we didn't ever try it. We've also really only dealt with the Jackson Racing unit on B series motors and the Comptech on the S2K. Only one of those could you really even think about running a real intercooler. I like your points tho, I'm sure you can do more with a blower today then when we worked with them but I'm all for turbo now... Just my opinion tho and that doesn't mean ****!

 

I run a fairly big turbo on the street. The only "problems" that I have are that with my clutch, I have to rev to 2500 rpms before letting the clutch go and it jumps forward (doesn't creep forward), the car takes about 3 min in warm weather and 6 minutes in cold weather to warm up (with Hondata S200), and obviously I have to cool the car if I run it hard (I don't have a turbo timer).

 

Okay, but the real question. Which is better on the engine in the long run? I've heard Turbos run down your engine on every day driving. Now of course both of them have their ups and downs but which on creates the most damage to your vehicle?

 

TurboGS-R are you just having problems driving it? If so you'll get used to it. All of our cars run Tilton twin disk cerametallics and there's not really a stiffer pedal out there for the streets but and we don't have to slip them from 2500rpm. As for "damage" to the motor it really depends on the power you're making and how you drive. Obviously parts will wear faster with more power (ie high boost turbo setups) but if you boost up around every corner with a SC you'll get the same affects. Superchargers are simpiler than turbos making for less things to break and from a dependabilty stand point you're probably better off as they don't make as much power, etc. I really don't look at it that way tho. How long do you want this motor to last? forever? Several of our turbo cars making 350-600whp have been running for ~3 years now driving them all the time on the street (not necessarily daily tho) and race every season. We don't baby them on the street either, it's fun to light up 4th on the freeway every once and awhile but it's not 28lbs. around every corner. In the long run if you really want to be dependable I'd say stick with your supercharger, don't boost a ton, and drive nicely...

 

good forum but in the long run... the only thing that matters is what u want to do because almost nething is possible now a ways... in some other words how deep are ur pockets....

 

Well, if you are looking at a daily driver, and it sounds like you are, supercharger is a good path. Your supercharger is controlled by vacuum pressure so you can cruise on the freeway, going 80, and boost nothing. In essence, it is there when you want it, not when you don't. Contrary to common belief, a boost controller can not turn boost completely off, so driving 80 on the freeway with a turbo you will be boosting. I have run a supercharger on my GSR from 115,000mi to the current 155,000 with no problems at all. I am happy with my dependability, but I have never had a turbo so they are possibly just as dependable.

 

I would agree with i3yron. for street driving or even road racing you'll find the powerband of the sc more usable. Don't get me wrong, I drive a 99 turbo gsr and I love it. However, the powerband is very peaky.

As far as the reliability question goes, it's all about turing. It is easier to up the boost on a turbo then it is on a sc. A lot of people like just turn up the boost with really knowing what they are doing. So in that case a sc in more reliable.
